Thank you that worked. I am just going to summarise the issue now for others:

When I started using the SC3336 camera on the Pico Ultra outdoors and notice the image is very washed out. I started to search for a way to adjust the contrast or sensitivity.

I tried the following:

Thank you,
I tried the following:

v4l2-ctl --device=/dev/video15 --list-ctrls

It produces:

Image Processing Controls: pixel_rate 0x009f0902 (int64) : min=0 max=1000000000 step=1 default=1000000000 value=102000000 flags=read-only, volatile

which does not look like what I am looking for.

I have started using the SC3336 camera on the Pico Ultra outdoors and notice the image is very washed out. Is there a way to adjust the contrast or sensitivity? I am running the buildroot build and streaming from the default RTSP setup.

I have a buildroot based image from which I can successfully stream.
On boot up RkLunch.sh runs and I can connect with VLC on: rtsp://192.168.1.206/live/0


I can then stop the streaming service with RkLunch-stop.sh:

RkLunch-stop.sh
Stop Application ...
killall: udhcpc: no process killed

I compiled again, made sure I ran RkLunch-stop.sh and can confirm the example worked. Thank you.

I also found some examples here: https://github.com/LuckfoxTECH/luckfox_ ... xample.git

Are these likely to work on the Pico Ultra?

I ran RKlunch-stop.sh before running the code

I tried that example and it does not work on the Pico Ultra.

Hi,

I am trying to understand what does and doesn't work on the Pico Ultra.

The SDK I am using is here: https://github.com/LuckfoxTECH/luckfox-pico.git

What does not work
1. Enabling OpenCV in the buildroot build. - It appears this version of openCV is not compatible with the board. I cannot ...

Hi,

I am looking for a simple example that allows me to capture a still image with the camera on my Luckfox Pico Ultra either using opencv or some other alternative.
I am familiar with the examples at https://github.com/LuckfoxTECH/luckfox_pico_rknn_example/tree/kernel-5.10.160
